include/: replace HTTP links with HTTPS ones

2020-08-12T17:57:59+00:00

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

pwm: omap-dmtimer: Drop unused header file

2020-03-30T16:03:06+00:00

pwm_omap_dmtimer.h is used only:
- to typedef struct omap_dm_timer to pwm_omap_dmtimer
- for macro PWM_OMAP_DMTIMER_TRIGGER_OVERFLOW_AND_COMPARE
Rest of the file is pretty mush unsed. So reuse omap_dm_timer
and OMAP_TIMER_TRIGGER_OVERFLOW_AND_COMPARE in pwm-omap-dmtimer.c
and delete the header file.

clocksource/drivers/timer-ti-dm: Implement cpu_pm notifier for context save and restore

2020-03-16T11:40:29+00:00

omap_dm_timer_enable() restores the entire context(including counter)
based on 2 conditions:
- If get_context_loss_count is populated and context is lost.
- If get_context_loss_count is not populated update unconditionally.

Case2 has a side effect of updating the counter register even though
context is not lost. When timer is configured in pwm mode, this is
causing undesired behaviour in the pwm period.

Instead of using get_context_loss_count call back, implement cpu_pm
notifier with context save and restore support. And delete the
get_context_loss_count callback all together.

clocksource/drivers/timer-ti-dm: Prepare for using cpuidle

2020-03-16T11:40:21+00:00

Let's add runtime_suspend and resume functions and atomic enabled
flag. This way we can use these when converting to use cpuidle
for saving and restoring device context.

And we need to maintain the driver state in the driver as documented
in "9. Autosuspend, or automatically-delayed suspends" in the
Documentation/power/runtime_pm.rst document related to using driver
private lock and races with runtime_suspend().

clocksource: timer-ti-dm: Make unexported functions static

2018-02-28T21:38:10+00:00

As dmtimer no longer exports functions, make those previously
exported static (this requires few functions to be moved around
as their prototypes were deleted).

ARM: OMAP: Move dmtimer.h out of plat-omap

2018-02-22T18:53:06+00:00

The header file is currently under plat-omap directory
under arch/omap. Move this out to an accessible place.

No Code changes done to the header file and renamed to timer-ti-dm.h.
